A) This happens when you terrace (with more then 1 segment) an odd shaped building (not having 4 nodes and squarish shape) with all versions of this plugin. This section of code is a bit complicated and I haven't looked at closely yet.

B) It also happens with version 21169 when you add a single address totally unnecessary (because there is nothing to terrace so the front and back don't have to be calculated). This particular problem (B) will be fixed in the next version.

Situation B is solved in version 21376.

Replying to Lambertus:

This section of code is a bit complicated and I haven't looked at closely yet.

If I recall correctly, this section is a bit of a hack. Feel free to rewrite it!
